    Revision 1.2  2000/01/05 08:20:39  markster
    Some OSS fixes and a few lpc changes to make it actually work
    
     * Revision 1.2  1996/08/20  20:31:21  jaf
     * Removed all static local variables that were SAVE'd in the Fortran
     * code, and put them in struct lpc10_encoder_state that is passed as an
     * argument.
     *
     * Removed init function, since all initialization is now done in
     * init_lpc10_encoder_state().
     *
     * Changed name of function from lpcenc_ to lpc10_encode, simply to make
     * all lpc10 functions have more consistent naming with each other.
     *
     * Revision 1.1  1996/08/19  22:31:44  jaf
